LTC1326CMS8-2.5#PBF

Supervisors Overview

The LTC1326CMS8-2.5#PBF is a supervisory circuit manufactured by Analog Devices Inc., designed for microprocessor monitoring applications. It features three independent voltage monitor inputs with threshold voltages of 3.3 V, 5 V, and an adjustable setting. The device operates within a supply voltage range of 1 V to 7 V and consumes a typical quiescent current of 40 uA. It provides configurable output types including active high, active low, and open drain configurations. A fixed reset delay time of 200 ms ensures stable power-up sequencing. The component maintains an accuracy of 0.75% and includes power failure detection capabilities. It is housed in an MSOP-8 surface-mount package and functions reliably across an operating temperature range of 0°C to +70°C.

Supervisors Feature Summary

• Monitors three distinct input voltages simultaneously for comprehensive system supervision
• Offers flexible output logic states to accommodate various interface requirements
• Integrates power failure detection for reliable data protection during brown-out events

Supervisors Applications

• Microprocessor power supply monitoring systems
• Battery-powered equipment requiring low standby current
• Industrial control units needing multi-rail voltage supervision

Supervisors Procurement Notes

Verify the specific suffix designation to confirm the exact threshold configuration matches the design requirement. Confirm RoHS compliance status through official manufacturer documentation before integration. Ensure the MSOP-8 footprint aligns with the PCB layout specifications. Check for any recent product change notices that may affect pinout or electrical characteristics.

Supervisors Selection Notes

Select this component when multiple voltage rails require simultaneous monitoring within a compact form factor. The adjustable threshold option allows customization for non-standard voltage levels. Consider the 200 ms reset delay duration against system startup timing constraints. Evaluate the 40 uA quiescent current impact on overall battery life expectations for portable devices.

Supervisors Part Context

This part belongs to the LTC1326 series of supervisory circuits from Analog Devices. It shares the MSOP-8 package and core monitoring architecture with other variants in the family. Different suffixes typically denote variations in threshold voltages or output configurations rather than fundamental functional changes.

Supervisors Replacement Considerations

Consult official Analog Devices documentation for verified cross-reference part numbers. Ensure any substitute supports three-input monitoring and similar electrical parameters.
